  Scaffolded bis-azasugars: A dual warhead approach to glycosidase inhibition

  摘要：

  Double Suzuki coupling was achieved with vinyl bromide 7, synthesized from the bromobenzene microbial oxidation metabolite bromocyclohexadienediol 6 and alpha,omega-diborane coupling partners derived from the hydroboration of the corresponding diene. Ozonolysis and selective reduction protocols served to provide selectively the aia or pip tethered polyhydroxylated piperidine ring systems (bis-azabugars). The C-8 linked DMJ analogue 1 showed inhibitory activity against glycosidase enzymes. (C) 1998 Elsevier Science Ltd. All rights reserved.

• Glycomimetics:  A Versatile <i>de Novo</i> Synthesis of β-1-<i>C</i>-Aryl-deoxymannojirimycin Analogues
  作者：Carl R. Johnson、Brian A. Johns

  DOI：10.1021/jo970585o

  日期：1997.8.1

  The synthesis of 11 beta-1-C-aryl-deoxymannojirimycin analogues using a versatile de novo strategy is described. The origins of this report are derived from several recent developments in the area of C-1-substituted glycomimetic polyhydroxylated piperidines. This study is designed as a structure-activity comparison to explore the effects of aryl substitution on the ability of the title compounds to inhibit glycosidase enzymes. The polyhydroxylated piperidine ring was constructed using vinyl bromide 10, which was synthesized in six steps from the bromobenzene microbial oxidation metabolite bromo diol 9. A palladium-catalyzed Suzuki cross-coupling of vinyl bromide 10 and the corresponding arylboronic acid served as the key pseudoanomeric carbon-carbon bond-forming step. Ozonolysis and selective reduction of the resultant carbonyl functions followed by reductive amination served to produce the azasugar ring. The complete NMR analysis of the resultant piperidine ring stereochemistry is also discussed. Fully deprotected beta-1-C-aryl-deoxymannojirimycin analogues 8.HCl were obtained upon acidic deprotection.

  日期：1997.11

  Methodology for the construction of diverse alpha-I-C-substituted-deoxymannojirimycin analogues is reported. The pseudoanomeric carbon-carbon bond was formed using a Suzuki cross-coupling between vinyl bromide 5, derived biocatalytically from bromobenzene, and an aryl, alkyl, or carbohydrate boron coupling partner. Ozonolysis and stereoselective reduction followed by an intramolecular nucleophilic ring closing served to form the polyhydroxylated piperidine ring. (C) 1997 Elsevier Science Ltd.
